Jaeger-LeCoultre Q1368430 Master Ultra Thin Moon Stainless Steel Silver Dial Watch

Jaeger-LeCoultre Master Ultra Thin Moon – Ref. Q1368430

The Jaeger-LeCoultre Master Ultra Thin Moon Ref. Q1368430 epitomizes refined elegance in watchmaking, blending minimalist design with technical sophistication. With its 39 mm stainless steel case, slim profile, moon-phase complication, and sun-ray silvered-grey dial, this model is perfect for those who value both understated luxury and reliable performance.

Case Dimensions

The case is crafted in polished stainless steel, measuring 39 mm in diameter and approximately 9.3 mm thick. This size delivers a presence without overwhelming the wrist. Water resistance is rated at 5 bar (≈ 50 meters), providing protection for everyday wear (rain, splashes) without compromising the elegant-dress watch character. Sapphire crystals cover both front and exhibition caseback to guard the dial and reveal the movement’s craftsmanship.

Dial Hands – Vision in Simplicity

The dial presents a sun-ray finished silvered-grey surface that catches light beautifully, giving dimension to an otherwise clean aesthetic. Dauphine hands carefully polished complement slim, rhodium-plated baton hour markers. At 6 o’clock, the moon-phase display with the integrated date subdial brings poetic complexity without cluttering the face. The seconds are centrally displayed. The overall visual is balanced and harmonious.

Movement Power Reserve

Powering the Q1368430 is Jaeger-LeCoultre’s in-house Calibre 925 (also listed in some sources as 925AA), a self-winding movement composed of 245 components and 30 jewels, beating at 28,800 vibrations per hour (4 Hz). The movement thickness is approximately 4.9 mm, helping maintain the slim profile. One of its major strengths is the 70-hour power reserve, giving substantial autonomy—nearly three days off the wrist without winding.

Strap, Clasp Wearability

The Q1368430 comes fitted with a black alligator leather strap, designed for comfort and elegance. It uses a stainless steel double-folding buckle to secure the piece. Strap dimensions are about 75 mm on the 12-o’clock side and 120 mm on the 6-o’clock side, with a lug width of 21 mm—ensuring a comfortable fit for many wrist sizes. The strap is interchangeable. The slim case and curved lugs help it sit flush, making it suitable under shirt cuffs or for dress occasions.
